The outcome of V vs. S shaped nasal deformity in preservation rhinoplasty; A comparative study

Preservation rhinoplasty resulted in a major change in the philosophy of rhinoplasty surgery, it include 3 main elements: elevation of a sleeve of skin from the subperichondrial-subperiosteal plane, preservation of the osseo-cartilaginous dorsum, and maintaining the alar cartilages with minimum excision while achieving the desired shape using sutures.

This is prospective study included 113 patients who underwent dorsal preservation rhinoplasty for nasal hump treatment. Patients were followed for 15months after surgery.

To compare the different outcomes between V-shaped and S-shaped dorsum regarding the cosmetic and functional outcomes after preservation rhinoplasty.

The mean age of our patients was 27.19years, females constituted 61.1%. Most patients (77.9%) had no complications after surgery, residual hump was the commonest in 13.3% of the patients, other complications were dorsal indentation in 5.3%, bleeding in 2.7%, and granuloma at the dorsal osteotomy site in 0.9% of patients. About 75.22% had S-shaped deformity, and the rest 24.78% had V-shaped deformity. The correlation was not significant between the types of the nasal hump deformity and the gender (P-value 0.395), age of patients (P-value 0.064), the overall postoperative SCHNOS for obstructive symptoms (P-value 0.19), the overall postoperative SCHNOS for aesthetic outcome (P-value 0.33), the postoperative complications (P-value 0.531), and the type of complications (0.705), while it was very significant with different postoperative SCHNOS scores for obstructive symptoms (P-value 0.000), postoperative SCHNOS different aesthetic scores (P-value 0.001), operation time and lowering the dorsal hump (P-values 0.000) for both.

Preservation rhinoplasty has low risk for postoperative complications. V-shaped deformity has a better overall outcome than S-shaped one.
